Puzzle.



To all whom iii may concern Be a known. that 1, JAMES amalgam a. citizen of the United States,resi'di1igat Syracuse, in the'county-of Onondaga and State of New York, have invented certain new and useful Improvements in ,Puzzles';

use the same.

This inventlon 1s a puzzle of that class wherein a predetermined number of movable elements bearing a designating number or figure are tobe arranged in such a manner as to produce a predetermlned sum 0 I result.

The invention contemplates aseries of rec Specification or Letters eaten ,h p i atiir filedjecemher l, 1915 tangular members or blocks, each bearing a figure or designation, the object being to so arrange the blocks in rectangular formation that the sum of each horizontal and each verticalrow of blocks, aswell as the sum of Figure 1 is a plan view of a series of rec tangular blocks having numerals thereon from 1 to 100; a

Fig. 2 designates an arrangement of the blocks with numerals from 1 to 80 so arranged that a space is left at the center of the group to facilitate moving the blocks within a receptacle.

In employing the puzzle with 100 blocks, numbered consecutively, the sum total of such numbers is 5050. Arranging these blocks in 10 rows of 10 blocks, each should total one-tenth of the whole, or 505. If it is desired to arrange the blocks in a con tainer with a shifting surface, then 99 blocks may be employed and numbered from 1 to 99' respectively, in which event, each row should total 495, by reason of the omissionof the block numbered 100.

In like manner, if 81 blocks are employed in'rectangular formation of .9 rows of 9 blocks each, the rows shouldtotal 369, or

rows to anner, 16.4; h

each :1 row to total 260, :such. number- ,being reame j Where-i9 .blo ck s. arehemployed, each.;, royv will total 175'"; the sum of a row where 36 block a exaernployed shou d; total. 111 ether:

blocks are employed should be 34-and where 9 blocks are employed in the puzzle, the sum of the row should be 15. In like manner, other combinations may be arranged.

Referring more particularly to the em- I bodiment of the invention illustrated in Fig; 1, a given number of rectangular movable members, 'or substantiallycubical blocks A are shown provided with a suitable indicating means ona face thereof. This indicating means, in the example illustrated in Fig. 1 is a numeral whereby the blocks areconsecutivelynumbered from 1 to 100.

In this arrangement of the device, the puzzle may be provided with blocks in consecutive order or variously assembled, the player being required to solve the problem by arranging the blocks A in the manner illustrated in Fig. 1, so that the sum of each vertical row B will total 505, each horizontal row 0 will total 505, and the sum of the diagonally arranged blocks D and E will one-ninth of the sum of 81 characters.

When a block is omitted to permit of the total 505. These blocks may be placed upon a flat surface and their relation changed by sliding theminto their variouspositions, or they may be bodily lifted and changed to various'positions, as desired.

In Fig. 2, however, I have illustrated an embodiment whereby a number of blocks, for example, 80 blocks, bearing numerals from 1 to 80 respectively, are so arranged in rectangular formation within a receptacle F that 8 rows reading from the vertical or horizontal are formed of 9 blocks each and one row reading from the vertical or hori 'zontal comprises but 8 blocks each, thereby leaving a space G, at substantially the cen-' tral part of the solved puzzle. This space "provides means whereby the various blocks may be shifted in the receptacle F to solve the problemof this arrangement, the sum of each of the 20 rows must be 360; that is, the sum of each of the 9 horizontal rows H should be 360,.the sum of each of the verti- I cal rows I should be 360 and the sum ofthe two main diagonal rows J. K., shouldbe 360. l

A vacant space may be left ,vanyvvhere in any arrangement of the squares-except'the one containing fifteen numbers; in that the nately to exhaust the Whole-1'00 numbers all totaling different amounts. 1 7

Having thus described my invention, what ters Patent oftheUnited States,-;is:" y *A puziz'le comprising a casing, a series of blocks being so arranged in rectangular formation withinthe'c a's'ing that a space is left -:for.-one block at substantially the center of vthe rectangular formation of blocks, where- ;.;by the s, u m,;of each vertical and horizontal row represented by the blocks Vandoof the "tWO main diagonah'rows will equal a predetermined amount. v v I V In testimony whereof; I afil'x my signature'yin presence of tvvo Witnesses.
